Application led March 30, 1914. Serial No. 828,205.

ployed in separating glasses from the lampl chimneys with which they areblown. rI`he invention has for its object theprovsion of a devicewhereby glasses ofluniform height are secured. One .embodiment of theinvention is illustrated' in the accompanying drawing whereinrIhe figureis a side elevation of the apparatus with the stopA device in section.

In separating glasses from the chimneys with which they were blown, ithas been customary to rotate the glass article about its axis, exposingthe periphery at the line of desired separationto a gas flame, thus seucuring a rupture at such line. rIhe position of the bottom if the glassduring this operation was determined by a stop bearing against thecenter of the bottom; As the bottoms of glasses are more or less uneventhe length of the glasses cut oif by this method varied, depending uponthe positions of the central portions of the bottoms of the variousglasses as compared with the periphery of the bottoms. In order toremedy this difficulty and secure glasses of substantially the samelength I employ a stop plate which engages the periphery of the bottomsof the glasses, such plate being 'preferably mounted for rotation andfor supported upon two pairs of disks 3 and 4,

only one disk of each pair being shown, and the construction in so faras these partslare concerned being well known in the art. The disk 3 isdriven from a sprocket 5, vthereby securing a rapid rotation of theglass article aboutits axis 6, while the disks 4 are merely idlers forsupporting the 'end othe chimney and are rotated by virtue of theircontact with such chimney. Adjacent the juncture of the chimney and theglass Ais a gas flame 7 for securing the separation of the chimney fromthe glass. l i

Mounted at the left hand end of the apparatus is the stop devicecomprising the casing members 8 and 9 held together by the screws 10 andthe stop plate 11. The stop plate 11 is pivoted at its center forrocking and rotary movement upon the end of the pin 12, such pin 12being carried by the stem 13 screwed into the casing member 9. 'Ihe stem13 passes through a ball 14 pivoted upon a pair of set screws 15 in theJfork 16. The ball 14 is provided with a set screw 17 for holding thestem 13 against movement through the ball. 'Ihis means :tor supporting astem for rocking and longitudinal movement is a well known expedient,and no claim is made for such detail of construction. The fork 16 isprovided with a stem 18 vertically-adjustable in the base 19 and bottom'of the glass 2, and that by reason of its support :tor universalmovement upon the pin 12 it is free to rock and adjust itself to thebottom of the glass. As a result the line 21 at which the glass issevered is determined and fixed by the bottom of the glass adjacent itsouter edge, since the principal portion of the bottom is somewhatdepressed and does not touch the plate 11. 'Ihe glasses as cut otl'l orseparated with this apparatus are therefore all substantially ofthe sameheight, since the mean distance from the line of contact between thebottom of the glass and the line of cutting off is the same in allcases.

What I claim is:

1. In combination, means for rotating a glass attached to another glassarticle about their common axis, a separating means adj acent theperiphery ci.f the glass, and a stop member for engaging the bottom 0Ithe glass on a line remote from its center and having a ball and socketmounting located at the' axis of rotation of the glass.

2. In combination, means for rotating a glass attached to a chimney withthe. axis thereof inclined downward tward'the bottom thereof, a devicefor securing the sepay ration of the glass and chimney' locatedadjacentthe juncture of the glass and chimney, and a stopplate mountedfoi-.rotation and adapted toengage the bottom of the g ass. 3. Incombination,V means for rotating a glass attached t0 a chimney with theaxis thereof inclined, a device for securing the separation of the glassand chimney located adjacent the juncture of the glass and chimney, anda stop plate mounted for rotation and for'universal rocking movement andadapted to engage the bottom of the glass. 4. .In combination, means for`axially rotating a cylindrical glass article attached to a glass havinga bottom extending transj Versely of the Walls of the glass, aseparating means adjacent the periphery of the glass and a stop memberfor engaging the bottom on a line remote from its center, the saidmember being mounted for rotary and rocking movement.

5. In combination, means for supporting a glass article attached to aglass having a bottom extending transverselyof the Walls of the glass, aseparating means adjacent the periphery of the glass, a stop member forengaging the bottom of the glass on a line remote from its centeradapted to be rotated by the glass, and means independent of the stopmember for rotating the glass.

In testimony whereof I have hereunto signed my name in the presence ofthe two subscribed witnesses.
